    This battery is completely compatible with my Garmin Fenix 3. It installed without difficulty, it took me 10 minutes to disassemble and reassemble. I managed to keep the double side on the watch to glue this new battery. Regarding autonomy, it is difficult for me to comment at the moment, not enough perspective since it has been installed for 2 days, but I have already noticed that in basic use with Bluetooth activated, it is this function which discharged my old battery very quickly, the autonomy is much greater.

    Unfortunately, the battery on my Fenix 3HR broke. The exchange was relatively easy. The new battery has the same dimensions, only the adhesive strip was missing. Double-sided carpet tape or something similar will help. The new battery has now lasted 4 days. So everything is great at the moment. I would buy the battery again at any time.

    Cette batterie est tout a fait compatible avec ma Garmin Fenix 3. Elle s'installe sans difficulté, il m'a fallu 10' pour le démontage, remontage. J'ai réussi à conserver le double face sur la montre pour coller cette nouvelle batterie. En ce qui concerne l'autonomie, il m'est difficile de me prononcer pour le moment, pa assez de recul puisque installée depuis 2 jours, mais j'ai déjà pu constater qu'en utilisation basique avec le bluetooth activé, c'est cette fonction qui déchargeait mon ancienne batterie très rapidement, l'autonomie est beaucoup plus importante.

    Leider war an meiner Fenix 3HR der Akku kaputt gegangen. Der Austausch war relativ einfach. Der neue Akku hat die gleichen Baumaße nur der Klebestreifen fehlte. Doppelseitiges Teppichklebeband oder ähnliches hilft da weiter. Der neue Akku hält nun schon seit 4 Tagen. Insofern im Moment alles top. Ich würde den Akku jederzeit wieder kaufen.

    Perfect, Installed without problems. I cannot assess the quality of the battery as it was installed only two days ago. Delivery within the agreed period.

    Perfecta, Instalada sin problemas. No puedo valorar la calidad de la batería al estar instalada hace solo dos días. Entrega en el plazo convenido.
